Network World reports that Apple has unexpectedly done away with the iOS 4.0’s jailbreak detection API, which comes as good news to many of those who have jailbroken their iPhones. As of now, there’s no way to check if a user’s iPhone has been jailbroken, making it susceptible to malware.

The news will undoubtedly worry some enterprise IT folks, as it leaves them with one less level of security protection to see whether an iPhone has been compromised. Why did Apple pull the plug? Only Apple knows and according to Network World, they declined to comment on the subject matter.
